You are welcome to send an item back, but we don’t offer an exchange service. You will need to order the item again in a different colour/size of your choice and we will treat this as a new order. You can either send the item that you don’t want back straight away for a refund (please read our full returns policy here - https://www.misupplies.co.uk/returns-information-i13) or wait until you are happy with the replacement item and then send it back. You have 365 days to return from the date of the order to return an item
